Sure! Here's a detailed and comprehensive answer to the question:

To assess the students' understanding of the 3rd unit "Earth and our place on it," I would design a summative assessment that covers various aspects of the topic. The purpose of this assessment is to evaluate the students' knowledge and skills acquired throughout the unit.

Step 1: Begin the assessment by including multiple-choice questions. These questions will test the students' factual knowledge about the Earth's characteristics, such as its layers, composition, and major landforms. Example questions could include:

1. What is the Earth's largest layer called?
a) Crust
b) Mantle
c) Core
d) Atmosphere

2. Which of the following is not a major landform?
a) Mountain
b) Ocean
c) Valley
d) Plateau

By including multiple choices, it ensures that students have a range of options to choose from and allows for easy grading.

Step 2: Include some short-answer questions that require students to explain concepts or provide examples related to the unit. This will assess their understanding and ability to apply knowledge. Example questions may be:

1. Define the term "erosion" and provide an example.
2. Explain how the position of Earth affects the seasons in different parts of the world.

In the short-answer questions, it is crucial to look for comprehensive responses that demonstrate a deeper understanding of the topic.

Step 3: Utilize diagrams or image-based questions. This type of question assesses students' ability to interpret visual representations related to the Earth and its place in the universe. For example:

1. Label the major layers of the Earth on the given diagram.
2. Identify and explain the process shown in the image related to plate tectonics.

Including visual elements in the assessment helps students visualize concepts and apply them to real-life situations.

Step 4: Incorporate problem-solving or critical-thinking questions. These types of questions evaluate the students' ability to analyze and make connections between different aspects of the unit. Example questions could include:

1. Imagine you are studying the impact of deforestation on the Earth's ecosystems. Discuss its consequences on the environment and suggest possible solutions.
2. Analyze the advantages and disadvantages of renewable and non-renewable energy sources in relation to their environmental impact.

Problem-solving questions encourage students to think critically and showcase their ability to analyze and evaluate complex issues.

Step 5: Finally, allocate a section for open-ended questions. This allows students to express their thoughts and understanding in their own words. Example questions could be:

1. Describe the importance of biodiversity on Earth.
2. Explain how human activities contribute to climate change, and suggest actions that can mitigate its effects.

Open-ended questions provide an opportunity for students to demonstrate a comprehensive understanding of the unit and showcase their critical thinking skills.

By incorporating a variety of question types, including multiple-choice, short-answer, image-based, problem-solving, and open-ended questions, this summative assessment ensures a comprehensive evaluation of the students' knowledge and understanding of the 3rd unit "Earth and our place on it."
